### Summary A web UI user can store files anywhere on the pyLoad server and gain command execution by abusing scripts. ### Details When a user creates a new package, a subdirectory is created within the /downloads folder to store files. This new directory name is derived from the package name, except a filter is applied to make sure it can't traverse directories and stays within /downloads. src/pyload/core/api/__init__.py::add_package::L432 ```python folder = ( folder.replace("http://", "") .replace("https://", "") .replace(":", "") .replace("/", "_") .replace("\\", "_") ) ``` So if a package were created with the name ```"../"``` the application would instead create the folder ```"/downloads/.._/"``` However, when editing packages there is no prevention in place and a user can just pick any arbitrary directory in the filesystem. src/pyload/webui/app/blueprints/json_blueprint.py::edit_package::L195 ```python id = int(flask.request.form["pack...

The Syrus4 IoT gateway utilizes an unsecured MQTT server to download and execute arbitrary commands, allowing a remote unauthenticated attacker to execute code on any Syrus4 device connected to the cloud service. The MQTT server also leaks the location, video and diagnostic data from each connected device. An attacker who knows the IP address of the server is able to connect and perform the following operations: * Get location data of the vehicle the device is connected to * Send CAN bus messages via the ECU module ( https://syrus.digitalcomtech.com/docs/ecu-1 https://syrus.digitalcomtech.com/docs/ecu-1 ) * Immobilize the vehicle via the safe-immobilizer module ( https://syrus.digitalcomtech.com/docs/system-tools#safe-immobilization https://syrus.digitalcomtech.com/docs/system-tools#safe-immobilization ) * Get live video through the connected video camera * Send audio messages to the driver ( https://syrus.digitalcomtech.com/docs/system-tools#apx-tts https://syrus.di...

Cap'n Proto is a data interchange format and capability-based RPC system. In versions 1.0 and 1.0.1, when using the KJ HTTP library with WebSocket compression enabled, a buffer underrun can be caused by a remote peer. The underrun always writes a constant value that is not attacker-controlled, likely resulting in a crash, enabling a remote denial-of-service attack. Most Cap'n Proto and KJ users are unlikely to have this functionality enabled and so unlikely to be affected. Maintainers suspect only the Cloudflare Workers Runtime is affected. If KJ HTTP is used with WebSocket compression enabled, a malicious peer may be able to cause a buffer underrun on a heap-allocated buffer. KJ HTTP is an optional library bundled with Cap'n Proto, but is not directly used by Cap'n Proto. WebSocket compression is disabled by default. It must be enabled via a setting passed to the KJ HTTP library via `HttpClientSettings` or `HttpServerSettings`. The bytes written out-of-bounds are always a specific co...

From Russia to Iran, the feds have charged Binance with allegedly conducting well over $1 billion in transactions with sanctioned countries and criminal actors.

A vulnerability in the web-based management interface of a small subset of Cisco IP Phones could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface on an affected device. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by persuading a user of an affected interface to view a page containing malicious HTML or script content. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker must have valid credentials to access the web-based management interface of the affected device.

A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to conduct an XSS attack against a user of the web-based management interface of an affected device.

Compromised websites are being used to redirect to fake browser updates and deliver malware onto Mac users.

Ubuntu Security Notice 6490-1 - Several security issues were discovered in the WebKitGTK Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.
